Feb. 13, 1934. J, F. CROWLEY v CAN, BOX, CANISTER, THE LIKE Filed Aug.24. 1932 Patented Feb. 13, 1934 UNITED STATES 1,947,382 can, Box,cameras, AND 'rnn LIKE John-Francis Crowley, London, England ApplicationAugust 24, 1932, Serial No. 630,302, and in Great'Britain August 26,1931 g 3 Claims. (01. 220-40) This invention relates to hermetic orvacuum closures for Jars, cans, boxes, canisters or the like, which arehermetically sealed under a vac uum, and are intended for containing andpre 5 serving foods or other substances.

The invention further relates to closures in which the container isclosed by a cover or cap having a depending flange or skirt which isadapted to flt over a flange on the top ormouth of the container whenthe cover is applied, and in which an elastic jointing-ring iscompressed be= tween a horizontal flange on the cover, and a horizontalshoulder or flange on the body of the con tainer when the container isclosed.

Closures for jars, bottles, cans or the like articles are known in whicha cover or cap flts upon the mouth of the jar or the like by means of abayonet joint or by means of partial threads to compress a rubberpacking ring lying between the cap or cover and a horizontal flange onthe Jar or the like.

According to the present invention, a jar, can, box, canister or thelike comprises a containerpart and a cap-part where both parts are ofmetal, or where one part is of rigid material, such as glass; one parthaving a horizontal flange adapted to receive an elastic packing ringand having an upstanding flange provided with a number of verticalspaces leading into a partial so or complete circumferential grooveimmediately above said horizontal flange. which spaces cooperate withpips or projections on the other part, which may either freely pass intosaid spaces, or alternately may frictionally hold upon the full diameterof the upstanding flange of the first-named part, adjacent said spaces,or again may pass into the partial or complete circumferential grooves.

' The invention is more particularly described 40 with reference to theaccompanying drawing in which:--

Figure 1 is an elevation partly in section of a canister according tothe present invention. with can.

enlarged scale in the vacuumizing position.

Figure 3 is a plan view of the alone of Figure 1. Figure 4 is anelevation partly in section oi a .6 modified form of construction.

Figure 2 is a sectional view of the parts'on an rubber packing ring 4,which has a pull-outtab 5. It will be seen that this packing ring 4 lieson a horizontal flange 3, which'overlaps inside and outside the canisterto equal extent. A groove 6 lies at the base of a vertical flange topartly accommodate the ring 4.

A number of axial grooves 8 are provided spaced around the flange orneck portion 7 to co-operate with pips 9 formed upon the cap 10, thelower skirt or rim of which is flared outwardly to provide a horizontalledge 11 adapted to bear upon a rubber ring 4 onthe ledge 3.

Now it will be seen that after the canister 1 has been fllled, the cap10 can be slipped axially directly upon the body 1, when the parts arein the position shown in Figure -1, and a tight seal will then beobtained by the normal vacuumizing process as shown in Figure 2.

In order to obtain access to the contents, the seal can be broken bytension on the tab 5, where- 76 uponthe cap 10 can be readily removed.

When it is desired to replace the cap 10, this can be pushed on the body1 so that the pips 9 come opposite a full flange portion 7, and therebythe cap is securely and frictionally held on the 80 body 1. W

The groove 6 need not be a complete one, but may bein the form of smallbayonet partial grooves, as shown at 13, Figure 4.

Although in the constructions described, the g5 .pressions 14 and 15respectively.

I declare that what I claim is:- l. A container including abody parthaving a horizontal packing flange and a neck portion upstandingtherefrom, said neck portion comprising a lower vertical portionadjacent said packing flange and an upper vertical portion of largerdiameter than said lower vertical portion, whereby a circumferentialgroove is provided on said neck portion adjacent said packing flange,said upper vertical portion being provided with vertical grooves whichmerge into said circumferential groove, anda cap part having a dependingskirt portion and a flange 'adaptedto cooperate with no said horizontalpacking flange, said depending skirt portion having projections adaptedto fit within said vertical grooves when the container is hermeticallysealed and adapted to be sprung over said upper vertical portion on saidneck portion when the cap part has been removed and slightly turnedwhereby said projections may engage the circumferential groove toprovide a triotion closure.

2. A container including a body part having a horizontal packing flangeand a neck portion upstanding therefrom, said neck portion beingprovided with vertical depressions which are difierentially spacedaround the periphery thereof. and a cap part having a depending skirtportion and a flange adapted to cooperate with said horizontal packingflange, said skirt portion being provided with difierentially spacedprojections whereby when the hermetic seal is broken,-said cap part mayhe forced into frictional engage= ment with eaidneok portion of the Topart.

8. A container including a body part having a horizontal packing flangeand a neck portion upstanding therefrom, and a cap part having adepending skirt portion conforming to said neck portion and a flangeadapted to cooperate with 10m FRANCIS CROWLEY. v
